How can the Messenger save us time and money?

There are few reasons to implement an AVL, engine diagnostic or remote monitoring solution unless there are tangible benefits. The Messenger provides engine, vehicle and operator performance information to allow owners/operators to:

Reduce downtimeKnow when equipment needs maintenance before a breakdown occurs. Engine diagnostics provide a good start, and monitoring other engine parameters over time provides a more complete predictive view. The Messenger reports diagnostics as well as exceeded operating limits and max and min conditions.
Reduce fuel usageBy knowing exactly how much fuel is used idling and working, used at high speeds, used at high RPMS, you can define the "sweet spot" of operation and save fuel.
Increase operator efficiencyCapture speeding, hard braking, fast accelerations and poor MPG to confirm non-optimal operator performance.
Perform maintenance on your scheduleBy precise reporting of engine hours, both idling and working, you can perform your maintenance on schedule. Or use the engine load values and switch to maintenance based on accumulated engine load.
Go GreenBy reducing the fuel usage you are reducing your carbon emissions - and have the data to prove it!
Increase equipment resale valueBy maintaining equipment to a higher standard the value of your equipment is greater when you sell it. Provide a detailed record of all manintenance faults to justify your price.
Eliminate theftKnow where your equipment is at all times and when it moves out of your defined geofences.
Reduce wear and tearBy setting operating limits and know when they are being violated.
Create employee incentivesBy knowing who follows company policies the best.
Better fleet and unit reportingAllowing managers to quickly compare and detail individual pieces of equipment or entire fleets. Click here to see reports created from Messenger data.
